How well you sleep may hinge on race
|
||
| The latest evidence that race and ethnicity can affect sleep came in June at the annual meeting of the Associated Professional Sleep Societies, held in Boston. In one of two studies on the topic presented there, white participants from the Chicago area were found to get an average of 7.4 hours of sleep per night; Hispanics and Asians averaged 6.9 hours and blacks 6.8 hours. Sleep quality ¡ª defined as ease in falling asleep and length of uninterrupted sleep ¡ª was also higher for whites than for blacks.[N. Y. Times] |
